, IMPROVEMENT IN GANG-PLOWS.

Specification forming part of Letters Patent No. 18,397, dated October 13, 1857.

To all whom it may concern:

Be it known that I, GEORGE W. HILDRE'IH, of the town of Lockport, in the county of Niagara, in the State of New York, have invented new and useful Improvements in Gang-Flows; and I do hereby declare that the following is a full and exact description thereof, reference be- To enable others skilled in the art to make. and use my invention, I will more fully describe its construction and operation, reference being had to the drawings, where the same letters refer to like parts in all the figures.

Figure l is a perspective view; Fig. 2, a side view of the gang; Fig. 3, a top view or ground plan of the gang; Fig.4, a longitudinal section of bolster-plate and tongue-iron; Fig. 5, an under side view of bolster-plate and tongue-iron; Fig. 6, a top view of bolster-plate and tongueiron; Fig.7,atransverseseetion of bolster-plate or front view; Fig. 8, a section of rear end ofthe frame, eyebolt, and axle; Fig. 9, a cross section of attaching-plates to sustain side pressure. Fig. 10, aland side view of the plow, showing attaching-plate on the plow, with bolt and hook to confine it to the frame, also showing the short and long landside. The brownish-red color represents the wrought-iron.

I construct the main frame in an elliptical form, of cast-iron, as seen in Figs. 1 and 3, A a a a, which frame has aflauge at the under side projecting each way from the upright part, with attaching-plates c 0 c for securing the plows to, and also forms a resting-place for the wrought-iron band or tire, which I shrink on hot, as seen in Figs. 1, 2, and 3, A A a, thereby securing strength and lightness for this purpose. 7

Icarry theforward end of the main frameA in Fig. 2 by an axle-tree having three distinct motions, or capable of three distinctmovements, namely: first, a semi-rotating motion to elevate or depress the wheels, (see Fig. 3, h h and E E5) second, a lateral motion between the plates, to make the furrow-wheel run in the furrow or out, as preferred; third, the vibrating motion on the center bolt, moving either end of the axletree and wheels fore and aft alternately by the pole, insuring the gang to follow the team much more accurately than when drawn by a chain in the ordinary way, also avoiding cramping in turning around.

The axle-tree h h, Fig. 3, has a crank on each end, upon which the wheels are put. I confine said axle-tree, which is round, between the two plates seen in Figs. 2 and at, at d, by making a half-circular groove in each plate fitted to the axle-tree, and with three bolts through said plates, as' seen at 'i "i i, Fig. 6. I clasp the axle-tree tight enough to hold it in any desired position, and by slackening the nuts on said bolts can move said axle-tree, as above described.

U in Fig. 3 is a handle for moving the axletree h h.

I connect the forward end of the main frame A in Fig. 2 with the axle-tree by using a round bolt, g, in Figs. 2 and 6, passing it through the plates D, Fig. 6, which bolt extends up through the frame A, with a nut on the top of said bolt, as seen at g in Fig. 2, and is also seen at g in Fig. 7, by which means the gang is turned around without cramping or crowding the wheels sidewise against the land, insuring ease to the team and implement.

I do not claim the arranging of plows in agang so as to turn several furrows atthe same time, nor the carrying it on wheels changeable in height; but

I do claim V The axle-tree, having a triple motion, in combination with the center bolt and bolster-plate, constructed and arranged substantiallyin the manner and for the purposes set forth.
